• Host AUv3 instruments, effects and MIDI effects inside the patch — and make sound without one: Synth, Wavetable, Drums, MegaSaw, Sampler and Slicer, with Drive, Filter, Delay, Reverb, Compressor, EQ, Chorus and Phaser, each with its own panel
• The Rack page — the audio side on one page: a strip per instrument with inserts, sends, sidechain, MIDI Learn, master inserts and scenes with fades; External Instrument channels for hardware
• Audio in, master and stem recording, Ableton Link, MIDI clock in and out, tap tempo, count-in, multi-output routing
• New sequencers — the Drum Grid (a whole kit in one lane), the Beat Map (an X/Y pad that blends drum patterns), the Metropolis-style Stage Seq, and a Chord Seq with rhythm, strum and voicing layers; patterns up to four bars, eight banks per lane, record into patterns, ratchets, custom scales, a patch key every lane follows
• Components — fold a cluster of nodes and its surface cards into one card with real ports; save it, drop it into any patch, edit it inside (graph editor)
• Players — tap the star on a lane and it writes a Drum, Drum Grid, Step, Analog or Chord Seq pattern from a style and a Complexity slider
• An arp on every keyboard, a MIDI FX slot on every track, New Patch templates and many more improvements across the board… more - 💰Konstrukt: price rise8.99 EUR → 17.99 EUR · DE

New
- Presets sync with iCloud and appear in Files as named .midirackpatch files. Organise them in folders, import and export them.
- Multi-page control surfaces with named pages and page-select buttons.
- Strings grid in any key: pick a root and scale, and glide stays pitch-true.
- Custom drum pad layouts: set every pad's note and label, or learn from your kit.
- Bluetooth MIDI pairing in MIDI Ports.
- Dockable inspector you can float or hide. Inspectors and the surface scroll by scrollbar so sliders never pan the view (switch back in Settings).
- Play from your computer keyboard: QWERTY piano, Z/X octave, C/V velocity, 1–8 and Q–I for drum pads.
- XY mode on the Seaboard and Strings surfaces: left-right sends pressure, up-down sends slide, independently.
- Apple Pencil expression: force plays the keys and pads, and drives pressure separately from slide on the MPE surfaces. Custom response curves per keyboard, with a live preview pad.
- CC pickers list standard controller names.
Fixed
- AUv3 failing to load in some hosts on iOS 18.
- AUv3 fits small host windows: compact chrome, a minimum size, and a scrolling surface.
- Keyboards and sequencer UI at one row high.
- Release bounce when dragging surface controls, and keys triggering through sheets.… more - 🆕Konstrukt released on the App Store

Konstrukt downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

Review momentum
52/100
faster than 54% of Music apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
What users say about Konstrukt
From the 5 most recent App Store reviews in the US.
Users highly praise the app's deep modular routing capabilities and responsive developer support, with several noting that reported bugs were fixed quickly. However, some reviewers highlight specific usability issues in landscape mode and request more advanced note division features.
Mostly positive (80% of recent reviews give 4–5 stars). Recent reviews are more negative than earlier ones.
About Konstrukt
Konstrukt is a patchable instrument for iPad and iPhone. Design the surface you play, sequence it, give it sound with built-in instruments and your own AUv3 plug-ins, mix and record it — and when you want to go deeper, unlock the visual graph underneath and rewire all of it. Standalone, and as an AUv3 in your host.
SURFACES YOU DESIGN
• The KB-1 keyboard suite — piano, diatonic chord pads, scale-locked keyboard, MPE Seaboard ribbon, MPE Strings grid (4ths) and a 4×4 drum-pad grid, each with an arpeggiator. Successor to the KB-1 Expressive Keyboard Suite.
• Knobs, faders, XY pads, buttons, live visualizers and channel strips on a snapping grid, in pages like hardware banks. Bind any control to MIDI CC — or, with the unlock, to any parameter in the patch.
A SUITE OF SEQUENCERS
• Drum, melody, chord, analog and CC lanes, the Drum Grid, a Metropolis-style Stage Seq and a Matrix note grid — tap to edit, with per-step velocity, probability, trigger conditions, ratchets and microtiming.
• Patterns up to four bars, eight banks per lane. Record into patterns step by step or live, then fix it in the grid. A Looper with quantize, undo and expression capture.
• Players: one tap on a lane writes a pattern from a style and a Complexity slider — drums with fills, a bass under your chords, chord stabs and pushes.
• One patch key and scale every lane can follow, custom scales, and chord lanes with their own rhythm layer.
INSTRUMENTS AND YOUR PLUG-INS
• Built in: a two-oscillator Synth, a Wavetable synth, Drums, MegaSaw, a Sampler and a loop Slicer, plus Drive, Filter, Delay, Reverb, Compressor, EQ, Chorus and Phaser — each with its own panel.
• Host your AUv3 instruments, effects and MIDI effects inside the patch (standalone app), with floating plug-in windows, presets and bindable parameters.
THE RACK
• A strip per instrument: fader, pan, mute and solo, inserts, pre- or post-fader sends to bus strips, sidechain, MIDI Learn, master inserts, and scenes recalled with a fade. Hardware synths join as External Instruments.
• Bring a mic or guitar in on its own channel. Record the master and stems to 24-bit WAV. Tap tempo, metronome with count-in, Ableton Link, MIDI clock in and out. Multi-output routing on a multi-channel interface.
UNLOCK — THE GRAPH EDITOR (in-app purchase)
Everything above runs on one visual graph that carries MIDI and audio. Unlock the editor to rewire it:
• 80+ node kinds — arps, scale quantizers, chords, echoes, swing, euclidean rhythms, LFOs and CC tools, wired MIDI In → processors → instruments or MIDI Out.
• Components — save a cluster of nodes as one card with real ports, its surface cards included; drop saved components into any patch and edit them inside.
• Audio on the same canvas — cable instruments through effect chains and hosted effects, split sends to buses, key a sidechain. The Rack is this graph seen as strips.
• Emergence generators — Game of Life, Turing machine, Wolfram rules, Markov chains, bouncing balls, a
